Complete the settings using the instructions below to suit your preferences.

Label when only flat rate shipping applies	Enter the text to use for the shipping rate when the only a flat rate for shipping will be presented and it is greater than zero. When left blank, “Shipping” will be used to describe the rate.
Label when only flat rate shipping applies and is free	Enter the text to use for the shipping rate when the only a flat rate for shipping will be presented and it is zero (e.g. free). When left blank, “Free shipping” will be used to describe the rate.
When the Flat Rate Shipping plugin…	There may be cases when the Flat Rate Shipping plugin and another of Eniture Technology’s quoting apps will both be asked to return shipping quotes. If the only rate received is from the Flat Rate Shipping plugin (the other plugin fails to return rate quotes for some reason) specify how to handle that case: Display only the flat shipping rate (Default) The flat shipping rate will be presented to the visitor and the visitor will still be able to complete the checkout process. Don’t display a shipping rate The result from the Flat Rate Shipping plugin will be suppressed. Unless there is another shipping method enabled for the shipping zone that is returning quotes, the customer will be unable to select a shipping method and will not be able to complete the checkout process.

Navigate to Products > All Products

Search for the product of interest, hover over its name in the search results and then click the Edit link.

Scroll down to the Product data section and click on the option for Shipping.

Locate the Flat shipping rate field and enter the flat shipping rate. For free shipping, enter a zero (“0”). Leave the field blank to allow the product to be included in the data set that is used to retrieve realtime shipping rates.

Enable the Multiply flat shipping rate by Cart quantity checkbox if you want the flat shipping rate for the item to be mulitplied by the quantity of it that are in the Cart.

Locate and click on the Update button which will normally be located at the top right corner of the page.

Repeat these steps for each product for which you want to offer a flat shipping rate or free shipping. If the product is a Variable product, refer to the Woocommerce documentation for instructions on how to manage their settings.

If the Cart contains only products that have the Flat shipping rate field populated, then the quoted shipping rate will be based solely on this setting and, if enabled, the Multiply flat shipping rate by Cart quantity setting. If there are other items in the Cart that are subject to realtime shipping rates retrieved by Eniture Technology’s LTL Freight Quotes or Small Package Quotes plugins, the realtime shipping rates will be retrieved first and then the results of the Flat Rate Shipping plugin will be added to them.
